Fragility Curves for Material Characteristics and Damage Index for Brick Masonry Exposed to Freeze–Thaw Action

open access: yesApplied Sciences, 2021
In regions exposed to floods followed by cold weather, brick masonry as a structural basis of the building envelope can be damaged due to the accompanying phenomenon of freezing and thawing.

Principal component analysis and perturbation theory–based robust damage detection of multifunctional aircraft structure [PDF]

open access: yes, 2013
A fundamental problem in structural damage detection is to define an efficient feature to calculate a damage index. Furthermore, due to perturbations from various sources, we also need to define a rigorous threshold whose overtaking indicates the ...

Association between serum Mg2+ concentrations and cardiovascular organ damage in a cohort of adult subjects [PDF]

open access: yes, 2020
Magnesium (Mg2+) levels are associated with insulin resistance, hypertension, atherosclerosis, and type 2 diabetes (T2DM). We evaluated the clinical utility of physiological Mg2+ in assessing subclinical cardiovascular organ damage including increased ...

Numerical Investigation of Seismic Performance of Steel Concentrically Braced Frames Subjected to Critical Consecutive Earthquakes [PDF]

open access: yesJournal of Rehabilitation in Civil Engineering
This paper evaluates the effect of critical successive-shocks on the seismic performance of steel concentrically braced frames (CBFs) for significant structural design parameters such as behavior factor(R), displacement amplification factor (Cd), maximum

Ion-implantation-caused special damage profiles determined by spectroscopic ellipsometry in crystalline and in relaxed (annealed) amorphous silicon [PDF]

open access: yes, 1993
We previously developed a fitting method of several parameters to evaluate ion-implantation-caused damage profiles from spectroscopic ellipsometry (SE) (M. Fried et al., J. Appl. Phys., 71 (1992) 2835).

Experimental Research on Shear Failure Monitoring of Composite Rocks Using Piezoelectric Active Sensing Approach

open access: yesSensors, 2020
Underground space engineering structures are generally subject to extensive damages and significant deformation. Given that composite rocks are prone to shear failure, which cannot be accurately monitored, the piezoelectric active sensing method and ...

Tensile strength estimation of paper sheets made from recycled wood and non-wood fibers using machine learning

open access: yesCogent Engineering, 2023
The deterioration of fiber properties during recycling processes, especially the loss of tensile strength, raises concerns that paper products made from recycled fibers might not satisfy quality requirements.
